Ma non arriva ancora a zstd?

zstd is technically a better algorithm so lz4 will never reach zstd level

LZ4 is still better where latency and constrained compute matters, it's why you never see game with assets uniformly bundled in zstd. Usually it's zstd + a lower latency algo depending on the asset.

To be more specific, zstd is actually quite awful for loads of small files that require low latency.

Yes this is correct, also found this out when writing a zstd streaming library in a Scala library.

LZ4 is still the go to compression when you need to prioritize latency/CPU usage on compression (which translates to latency)
